Which is Better Drum or Disc Mower | You Need to Know

which is better drum or disc mower

When evaluating the choice between drum mowers and disc mowers for your hay-growing needs, it’s essential to consider their fundamental design differences. 

Drum mowers, characterized by two or three large belt-driven drums, are known for their cost-effectiveness and ease of maintenance. These features make drum mowers a practical choice, particularly for those seeking affordability and straightforward repairs.

On the other hand, disc mowers operate with numerous smaller shaft- or gear-driven discs. This design variation allows disc mowers to boast larger cut widths and enhanced performance compared to their drum counterparts. 

The increased efficiency of disc mowers becomes evident in their ability to handle a more substantial workload, making them a preferred option for those prioritizing productivity and cutting capacity.

In the realm of hay-cutting machinery, the debate between drum and disc mowers often revolves around the balance between cost-effectiveness and cutting capabilities. 

It’s crucial to align your choice with the specific needs of your hay-growing operation, considering factors such as budget constraints, maintenance preferences, and the scale of your harvesting requirements. 

Ultimately, whether you lean towards the economic simplicity of drum mowers or the performance advantages of disc mowers, the decision hinges on finding the right balance for your unique circumstances.

How Does a Drum Mower Work?

In the regions surrounding Lexington and Louisville, the adoption of drum mowers is gaining momentum, prompting curiosity about how a drum mower works. 

Fundamentally, a drum mower operates by employing two or three substantial plates, aptly named drums.

As you navigate your terrain, the drum mower adeptly slices through the grass, leaving a neat trail of cut vegetation in its wake. The efficiency lies in the seamless process of cutting and laying the grass behind the equipment, streamlining the mowing operation.

Unlike some mowers that disperse cut grass in a wide swath, drum mowers follow a different approach. 

The cut grass is neatly laid out behind the mower, necessitating an additional step – tedding – to facilitate proper drying. This distinctive feature distinguishes drum mowers and underscores the importance of complementary tasks for optimal haymaking efficiency.

How Does a Disc Mower Work?

In the evolution of mowing technology, older disc mowers consolidated their blades into a single large apparatus, a design that contrasts sharply with modern disc mowers

The contemporary counterparts utilize numerous smaller discs, each housed individually. This not only enhances efficiency but also simplifies the repair process, a notable improvement over their older counterparts. 

However, for those who prioritize simplicity and ease of use, drum mowers still maintain their appeal.

Now, delving into the mechanics of how a disc mower operates, each smaller disc mirrors the functionality of the drums in traditional mowers.

A key distinction lies in their weight and support requirements—disc mowers are generally heavier and often necessitate hydraulic support for optimal functioning. 

Despite being larger and capable of cutting a wider swath, disc mowers lag behind drum mowers in terms of speed, with the latter demonstrating a quicker operational pace.

A significant consideration in the debate over drum versus disc mowers revolves around their suitability for hay-drying operations. Disc mowers gain an upper hand in this domain due to the effective spreading of hay facilitated by the smaller discs

This inherent advantage makes disc mowers a preferred choice for hay drying, even when both types can be equipped with conditioners to aid in the drying process. 

The nuanced features of each mower type contribute to a dynamic landscape in agricultural machinery, with users weighing factors like swath width, speed, and drying efficiency in their decision-making process.

Drum vs. Disc Mowers: Which is Right for You?

Choosing between drum and disc mowers depends on various factors, including your specific needs, the type of terrain you’re working with, and your budget. 

Both types of mowers have their advantages and disadvantages. Here’s a brief comparison to help you decide which might be right for you:

Drum Mowers

  • Simplicity and Durability

Drum mowers are known for their simplicity in design, making them durable and requiring less maintenance.

They have fewer moving parts compared to disc mowers.

  • Affordability

Drum mowers tend to be more budget-friendly, making them a good choice if cost is a significant consideration.

  • Suitable for Rough Terrain

Drum mowers perform well in rough and uneven terrain.

They can handle tall and dense grass without clogging as easily as some disc mowers might.

  • Ease of Repair

Because of their simpler design, drum mowers can be easier to repair for someone with basic mechanical skills.

Disc Mowers

  • Faster Cutting Speed

Disc mowers generally have a faster cutting speed compared to drum mowers, which can lead to increased efficiency.

  • Better Cutting Quality

Disc mowers often provide a cleaner and more precise cut, making them suitable for hay production and high-quality forage.

  • Versatility

Disc mowers are versatile and can handle a variety of crops, including legumes and forage.

  • Adjustability

Many disc mowers offer adjustable cutting height, allowing you to customize the cutting height according to your needs.

  • Suitable for Large Areas

Disc mowers are often preferred for large fields due to their faster operation and efficiency.


  • Field Conditions

If you have rough and uneven terrain, a drum mower might be more suitable.

For smoother fields with a focus on forage quality, a disc mower might be the better choice.

  • Budget

Consider your budget constraints, as drum mowers are generally more cost-effective.

  • Intended Use

Determine the primary purpose of your mowing (e.g., forage production, haymaking) to guide your decision.

  • Maintenance

Evaluate your comfort level with maintenance tasks. Drum mowers are often simpler to maintain.

  • Field Size

For larger fields, the speed and efficiency of disc mowers might be more beneficial.


In conclusion, the choice between a drum mower and a disc mower ultimately depends on specific agricultural needs and preferences. 

Both types of mowers have their advantages and disadvantages. 

Drum mowers are known for their simplicity, lower cost, and durability, making them suitable for less demanding conditions. 

On the other hand, disc mowers offer a more precise and efficient cutting mechanism, particularly in dense or wet grass, but come with a higher initial cost. 

Farmers should carefully assess their terrain, budget constraints, and desired features to make an informed decision on whether a drum or disc mower is better suited for their particular farming operations.


What is the primary difference between a drum mower and a disc mower?

A drum mower utilizes a cylindrical drum with blades, while a disc mower has rotating circular blades. The fundamental distinction lies in the cutting mechanism and the shape of the cutting components.

Which mower type is more suitable for rough or uneven terrain?

Disc mowers are generally considered better for rough or uneven terrain. Their design allows for better ground contour following, reducing the risk of scalping or uneven cutting compared to drum mowers.

What are the advantages of using a drum mower?

Drum mowers are often praised for their simplicity and durability. They have fewer moving parts, making them easier to maintain. Additionally, drum mowers are less prone to damage from rocks or debris in the field.

Why might someone prefer a disc mower over a drum mower for large-scale operations?

Disc mowers are favored in large-scale operations due to their wider cutting widths and faster cutting speeds. They can cover more ground in less time, making them more efficient for larger fields.

In terms of cut quality, which mower type is generally considered superior?

Both drum and disc mowers can provide high-quality cuts when properly adjusted and maintained. However, disc mowers are often preferred for producing a cleaner cut, especially in crops like hay, thanks to their precise cutting action.
